CAR-COUPLING.

"np ilieatiofifiled January 26, 1914. Serial No. 814,507.

To all @071 0m it may concern:

provements in Car-Couplings; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in car couplings, and particularly to means for lifting the locking block to uncouple or release the knuckle, and it consists in the details of construction as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in front elevation of a car coupling embodying our invention, and Figs. 2 to 6 inclusive are views of modified forms.

1 represents a coupling head, and 2 the knuckle which latter is locked in closed position by a vertical sliding pin or locking block in the well known manner, The lower end of the pin or block is accessible through an opening in the bottom of the head, so that it may be engaged by the free end of the finger 3 of the bell crank leverl. This lever 4 is pivoted at 5 to the bracket .6, shown in dotted lines in Fig. 1, which bracket is cast integral with the head 1, and the lever is normally sustained with its finger 3 out of contact with unlocking mechanism but actually extending through the opening in the floor of the head, and under the locking pin or block by the extension P of the lever bearing against the head of the coupling as will be hereinafter more fully explained, and it is actuated by the pitman 7, pivotally connected at 8 to the depending integral extension 9 on lever 4c, the extension having a hole through same for the attachment of the pitman 7.

The pitman 7 extends upwardly and has a universal connection with the arm 10 of the rock shaft 11 the latter being pivotally secured to the end sill, or front of the car, and is provided at each end with an arm 12 by which the shaft 11 may be rocked.

Lever 4 is provided with an upward extension 4, from its hub, which latter projects up along the side of the head and is provided at its upper end with an inwardly projecting toe 4: which engages the side of specification of Letters Patent.

Manama. in, 'i'eia.

the coupling head and limits "the drop'bf the lever, so that its weight, and the weight of the pitman will hold its toe 4 against the head and prevent any downward swinging movement of the lever. When in this position the finger 3 of lever 4 is just below and out of contact with the locking pin and block, but is maintained within the recess in center of head provided for it, thus using the bottom of draw head as a guide for finger 3.

In the construction shown in Figs. 2, 3 and 4 the upward extension 4* of the lever is enlarged laterally so as to bear on the top of the bracket 6, instead of against the side of the coupling.

In the construction shown in Fig. 5, the upward extension of the levers bear against the rear wall 6* of the bracket 6, while in the construction shown in Fig. 6, the upward extension has an inwardly proiecting toe 4 which rests a ainst the outwardly projecting shelf 15, which maybe integral with the coupling head, but which is preferably also integral with the bracket 6.

Normallv the lever 4 stands in the position shown in Fig. 1. and when in such position, its finger 3 is down and is not lifting the pin or locking block. By pulling up on the pitman, the finger 3 moves upward in the coupling head and engaging the locking pin or look lifting means, lifts the same a distance sufficient to release the knuckle. When the lever is released it drops to the position shown in Fig. 1, but as the upward extension thereon engages an abutment before the lever reaches its center of gravity the latter will beheld in proper position.

Having fully described our invention what we claim as new and desire to secure by Letters-Patent, is

1. The combination with a coupling head, a bracket projecting from the same, a lever pivoted adiacent its upper end to said bracket and lifting means connected with said lever adjacent the free end of the latter, the said lever being also provided adjacent its free end with a finger ada ted to pass through the floor of the coupling for raising the knuckle locking means. and at its other or pivoted end with a shoulder to engage the bracket for limiting the drop of the lever.

2. The combination of a coupling head, a bracket projecting from same, a lever pivoted adjacent its upper end to said bracket In testimony whereof, wehave signed this 10 and provided at its opposite end with a finspecification in the presence of two subscribger adapted to pass through the floor of the ing witnesses.

coupling for raising'the knuckle locking GEORGE T JOHNSON means, the said lever being provided at its GEORGE M MURPHY upper end with a shoulder adapted to overhang the bracket and limit the drop of the Witnesses: lever, and means for actuating the said V. E. PAGE, lever. F. G. BENNETT.
